Benefits of technology
The present invention provides a method and apparatus for manufacturing an image display apparatus by efficiently performing various kinds of processing without disturbing the use of a seal-bonding material with a high seal-bonding temperature. The method involves subjecting panel members to bake processing and then combining and seal-bonding them in a seal-bonding processing chamber. The temperature of the panel members is lowered after bake processing and they are brought into the seal-bonding processing chamber where they are locally heated to conduct seal-bonding processing. The apparatus includes a plurality of processing chambers including a bake processing chamber, a seal-bonding processing chamber, and one or more intermediate processing chambers which are intervened between the bake processing chamber and the seal-bonding processing chamber. The temperature control means are set to the previous processing chamber or lower to efficiently control the temperature of the panel members. The technical effects of the invention include improved production efficiency and quality of the image display apparatus.
Problems solved by technology
This provides a problem in that a processing time is long and efficiency is poor.

Abstract
A method of manufacturing an image display apparatus is provided and includes the steps of bringing panel members that constitute a display panel of the image display apparatus into a bake processing chamber, subjecting to bake processing the display panel members, lowering a temperature of the display panel members, and bringing the display panel members into a seal-bonding processing chamber. Seal-bonding processing is conducted by local heating to a seal-bonding portion.
Description
BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a method of manufacturing an image display apparatus which includes the steps of: performing bake processing to panel members constituting a display panel of the image display apparatus; and combining and seal-bonding the members, thereby forming the display panel and to an apparatus for manufacturing the image display apparatus.[0003]2. Related Background Art[0004]Up to now, as a method of manufacturing an image display apparatus which includes the steps of combining and seal-bonding panel members that have undergone bake processing, thereby forming a display panel, such a method is known in which: panel members are placed in a vacuum chamber and subjected to bake processing; moisture and gas components, which are adhered or adsorbed to the panel members, are removed; also, the vacuum chamber is exhausted to obtain a predetermined depressurized condition; and then, the panel members are...
